Description

Key features

Maximum Property Class 12.9Quenched and tempered from high-performance alloy steel, delivering a nominal tensile strength of 1200 N/mm² and yield point of 1080 N/mm² to prevent bolt elongation, shear deformation, and brittle fractures during rocky soil impact.

Metric Fine Thread Pitch (M14 × 1.5)The fine 1.5 mm pitch provides superior self-locking resistance against persistent working vibrations compared to coarse threads, ensuring consistent preload retention and clamping force.

Precision 24 mm Unthreaded Solid ShankKeeps the critical shear boundary between the blade and mounting flange completely on the solid unthreaded body, preventing notch stress concentrations on the thread and eliminating mounting hole elongation.

Supplied Complete with Matched NutPaired with an extra high-strength matching nut suited for class 12.9 torque specifications, optimized for standard dual-bolt tine installations (typically 2 sets per blade).
